I am having trouble properly configuring this AT&T 2Wire 3600HGV modem for my network. Maybe someone is aware of a different firmware for this product?

I am completely aware of how to setup the DMZ mode & router behind router setup in these boxes but that is NOT the point. (We have supported firewalled networked equipment working that has all the bells & whistles including QoS)

In the event of a factory reset of the AT&T 2Wire VDSL modem at this business, I want to properly insure the following business requirements are met:

- DHCP - OFF (at min, it appears you must leave one available?)

- WiFi - OFF (Yes this can be turned off, but bridging it always insured it was turned off in the past. ON is a security concern among just bad business i.e. conflict with other business WiFi, employees might see/use this non-content filtered WiFi, etc etc)

- & passing off internet service needs to be easy to another networked supported OUTSIDE of AT&T firewall. (I'm NOT asking for AT&T support on this, but in the bridge DSL world, this was EASY)

- if bridging this 2Wire is NOT an option, backing up the configuration settings would be a nice alternative but that is not available as well?

Bridging the old DSL modems always worked nicely but the 2Wire 3XXXHGV line appears to be the ONLY ones to support the AT&T VDSL Max Turbo speeds. 24Mbps down / 3 Mbps up which we use not only for normal business operations (credit cards, business email, web based training, etc) but this high speed is required to view onsite security video (3Mbps up) and offer customers FAST free WiFi!

AT&T U-Verse offers the right price, contract, speed, internet package & installers to properly handle our resturant locations company's data needs but I'm struggling with the their "business" support of this 2Wire VDSL modem product. We ONLY use the internet, no TV (not legally available for restaurants, yet). No Voip because POTS is our reliable backup. So it's just the internet service ...

For coverage on AT&T Uverse, we have over 50 locations lit up like a Christmas tree but sadly business support on this product is driving me nutz! Maybe because I now see this is listed under "Residential Gateway"? Is this AT&T 2Wire VDSL modem product not meant for business? Is anyone aware of another supported AT&T VDSL modem or a different 2Wire firmware available? Official AT&T support has me running in circles (AT&T U-verse support > AT&T Connecttech > AT&T Connecttech360 > AT&T U-verse support, rinse, repeat)

8. Restart your router, when it gets an address via DHCP again, it will be the public outside IP address. At this point, you can leave your router in DHCP mode (make sure the firewall on your router allows the DHCP renewal packets, which will occur every 10 minutes), or you can change your router's IP address assignment on the WAN interface to static, and use the same settings it received via DHCP.

I just got a new wireless router and I'm trying to set it up as per your instructions. (I did this before successfully a few years ago, but I can't remember how). Anyway, I've followed your instructions, and everything seems set up correctly. The router is getting an outside ip address. My wireless devices are connecting fine with a valid ip address from the router's dhcp. But, I get no internet. I also have a desktop computer plugged directly into the router, and it has no internet. The rest of the computers on my network are all working fine. The only possible deviation is that the router is not plugged directly into the 2Wire, but is plugged into a switch connected to the 2Wire that all my other computers are connected to. Would that make a difference?

Any help is appreciated.

One other thing that I just noticed: when looking at the connection info on my iPhone, it's showing the DNS address as the same address as the wireless router (it's actually showing that address twice). That sounds suspicious to me.

If devices that are connected to your router are getting DNS addresses that are the same as your router, that is correct. Most home routers act as a DNS server, so they hand out their own address as the DNS server. The router then forwards the DNS requests to the upstream DNS server.

Check your subnetting on the 2Wire RG and on your router carefully. By default, the U-Verse RG's DHCP range is set to 192.168.1.x. This is the same DHCP range that many home routers hand out. If the two DNS ranges are the same, Internet will not work. You must change the LAN addressing of your router to 192.168.2.x (router address: 192.168.2.1), or you must change the 2Wire DHCP range on this page:

OK, that's what I've found out also - I had both routers on the same subnet. If the wireless router is on a different subnet, everything works fine. My problem is this - I need to be able to access all the devices on the network. I can't access files on a computer that's on a different subnet. How do I get around this?

In that case, you do not want to follow these directions at all, since you do not need special routing functionality. Instead, all you want is a wireless access point.

To do this, do the following:

1. Turn off DHCP on your router.

2. Change the link between the 2Wire router and your router to use the LAN ports on both ends. (In other words, plug the cable from one of the LAN ports of the 2Wire to one of the LAN ports of your router. Leave your router's WAN port empty).

3. Change the LAN IP address of your router to a static IP on the same subnet as the 2Wire router. For example, if the 2Wire router is using 192.168.1.x, and the DHCP range is 192.168.1.64 - 192.168.1.253, set your router to 192.168.1.10.

4. If necessary, configure the wireless parameters on your router, such as SSID, encryption, pre-shared key, and MAC filtering.

Your wireless computers connected to your router will now be able to communicate with wired computers on the 2wire router since everything will be on the same subnet.

I have read your posts under this topic and also under the “Router behind Router Setup…” topic in this forum. Thanks for the info. At the moment I have a Linksys WRT160N router coupled to an AT&T DSL modem. I am subscribing to UV Internet MAX (no TV or VoIP) and I am getting a 2WIRE-3801 gateway. I would like to set up my Linksys router as a wireless access point as I prefer Wireless N and WPA2 to the Wireless G and WPA that comes with the 2WIRE. If I set up the router as a wireless access point as you describe in Message 13 here (I assume that I should turn off the wireless on the 2WIRE also), will I have any kind of firewall protection, either from the UV gateway or the Linksys? I do not need any special router functionality other than the wireless but I would like to have the extra protection that the router is now providing me with my current DSL setup. Would you please elaborate on this? Thank you.
